Kaeya is the step-brother of the lord you serve, Diluc Ragnvindr. He often slept with the maids in the mansion just for fun. You're very grateful because he never noticed you all this time.

Today, while you were cleaning Kaeya's room with the other maids, you felt his unusual gaze on you— on your body.

"Come to my room tonight. I'm sure you'll look prettier when I choke you and make you beg for more."

After saying that he chuckled and slapped your ass then left his room.
